- Bugs -- known problems in the shell.
-
- The "suspend" built-in command is *very* naive. E.g. cranking up a
- subshell from vi, and then suspending it, will leave you sort of in limbo.
- A control-Z will then suspend the vi. Then a 'fg' command foregrounds the
- stopped sub-shell. Control-D'ing the subshell puts you back in vi.
-
- If the shell is being run from a terminal, and you interrupt it in the
- middle of doing a here document (cat << FOO ..., interrupt before the FOO),
- then if history was turned on, you will be left with history turned off.
- Use set +H to turn it back on.
-
- I do not have access to a PDP-11, so there will probably be problems
- trying to move this stuff to a small address space machine. Let me know
- what you encounter, and I will encorporate any diffs that people send back
- to me.
-
- A recent posting in net.micro.att indicated that the Unix PC's window
- manager uses $HOME/.history to save things. This is also the default for
- where this history mechanism keeps things -- change the value of HISTFILE in
- your .profile to be something different, and export it, if you're on a Unix PC.

- ****************
-
- There are probably bugs in the code I have added to the shell.
- I think I have caught everything, but I can't guarantee. If you discover
- any problems, please let me know, so that I can track them down and fix
- them.
-
- I regard this as a "first iteration." In other words, I will not be suprised
- if there are bugs. I am counting on the net to be friendly enough to let
- me know about any that may be discovered. I am also open to suggestions for
- other fixes or additions to the shell. As things come in to me, I will
- incorporate what I can, and hopefully post a new set of revisions.
-
- Meanwhile, enjoy!
